More thoughts on Plex Panels:  If you want a clear panel I would 
recommend Plex rather than polycarbonate or Lexan.  I believe Plex 
is more resistant to scratching.  If you want a tough durable 
plastic use ABS.  As someone else mentioned ABS is the plastic used 
in car interiors.  It drills and cuts far easier than Plex, but I 
doubt you can get it in transparent.  If you are going to glue 
anything to it a special glue is required as it is too slippery for 
most plastic glues.  Even epoxy will not adhere to it.  For a really 
unique panel drill your Plex, put clear labels with white letters on 
the back side (so you can read them through the Plex), then spray 
the backside black over the letters.  Be sure the paint you use 
doesn't dissolve the lettering.  You could also try printing a full 
size panel on your computer printer and putting that on the backside 
of the Plex.  If you try this probably inkjet is best as you need a 
really dark black.  As you can probably tell I've been experimenting 
with making panels for a long time.
